P-satI-D Shape Regulation of Soft Robots

Soft robots are intrinsically underactuated mechanical systems that operate under uncertainties and disturbances. In these conditions, this letter proposes two versions of PID-like control laws with a saturated integral action for the particularly challenging shape regulation task. The closed-loop system is asymptotically stabilized and...

Integrative Robo-Ethics: Uncovering Roboticists’ Attitudes to Ethics and Moving Forward

This article proposes an integrative approach to robotics research, based on bringing interdisciplinarity into the lab. Such an approach will facilitate researchers across various fields in gaining a more nuanced understanding of technology, how it is developed, and its potential impacts. We describe how a philosopher spent time embedded in...

A policy framework for the circular economy: Lessons from the EU

Transitioning from the ‘take-make-dispose’ linear production system to a circular economy can strengthen sustainability, and governments play a vital role. Recent scholarship has investigated policies for circular economy transition, but few studies take a perspective on circularity reform that spans geographies, industries, and product life...

Robust Output Regulation: Optimization-Based Synthesis and Event-Triggered Implementation

In this article, we investigate the problem of practical output regulation, i.e., to design a controller that brings the system output in the vicinity of a desired target value while keeping the other variables bounded. We consider uncertain systems that are possibly nonlinear and the uncertainty of their linear parts is modeled element wise...

Getting in control of persistent, mobile and toxic (PMT) and very persistent and very mobile (vPvM) substances to protect water resources: strategies from diverse perspectives

Background: Safe and clean drinking water is essential for human life. Persistent, mobile and toxic (PMT) substances and/or very persistent and very mobile (vPvM) substances are an important group of substances for which additional measures to protect water resources may be needed to avoid negative environmental and human health effects. PMT...

A Mode-Switching Based Phase Shift Control for Optimized Efficiency and Wide ZVS Operations in Wireless Power Transfer Systems

This article proposes a mode-switching-based phase shift control (MS-PSC) for wireless power transfer (WPT) systems, which is able to achieve power regulation, load matching, and wide ZVS operations simultaneously without using additional dc-dc converters. Based on the mode transitions between the full-bridge, mixed-bridge, and half-bridge...

Making the most of short-term flexibility in the balancing market: Opportunities and challenges of voluntary bids in the new balancing market design

Electricity balancing is one of the main demanders of short-term flexibility. To improve its integration, the recent regulation of the European Union introduces a common standalone balancing energy market. It allows actors that have not participated or not been awarded in the preceding balancing capacity market to participate as voluntary...

How deregulation can become overregulation: An empirical study into the growth of internal bureaucracy when governments take a step back

Over the past decades, government safety management regulation has been driven by deregulation, simplification and organization-level regimes of inspection. So-called functional rule-making requires organizations to implement safety management systems appropriate for their operations. The paradox that seems to have arisen is that...

Distributed energy resources and the organized balancing market: A symbiosis yet? Case of three European balancing markets

Thanks to new technological advancements and EU policy impulse, distributed energy resources (DER) are poised to become a viable alternative to conventional electricity generation for the provision of balancing services to transmission system operators. In this paper we show that the design variables that affect DER access to and...

Multi-mode standardisation: A critical review and a research agenda

Standardisation is key to shaping new technologies and supporting major ongoing trends, such as the increased importance of platforms, developing 'smart' technologies and innovating large-scale complex systems. Standardisation plays a key role in shaping the rules that govern these developments and their effects on society. Due to the large...

Market integration of local energy systems: Is local energy management compatible with European regulation for retail competition?

The growing penetration of distributed energy resources is opening up opportunities for local energy management (LEM) – the coordination of decentralized energy supply, storage, transport, conversion and consumption within a given geographical area. Because European electricity market liberalization concentrates competition at the wholesale...
